Step 1

If desired, cut a small slice off the bottom of each squash half to help it rest flat. Sprinkle the insides with a pinch of salt and 1/8 teaspoon pepper. Place in a 8-inch-square (or similar-size) microwave-safe dish. Cover with plastic wrap and microwave on High in 4-minute bursts until the squash is fork-tender, 8 to 12 minutes.

Step 2

Meanwhile, heat 1 tablespoon oil in a medium skillet over medium heat. Add leek, celery and mushrooms. Cook, stirring occasionally, until beginning to brown, about 5 minutes. Add garlic and cook, stirring, for 1 minute. Add wine and cook, stirring, until mostly evaporated, about 1 minute more. Add wild rice, bread cubes and herbs. Stir in broth and the remaining 1/4 teaspoon salt and 1/8 teaspoon pepper. Cook, stirring, until heated through and the broth is absorbed; about 1 minute.

Step 3

Position rack in center of oven; preheat broiler.

Step 4

Fill each squash half with the stuffing mixture (about 1 cup each). Place in a baking pan or on a baking sheet. Drizzle the stuffing with the remaining 1 tablespoon oil. Broil in the center of the oven until the stuffing is beginning to brown, 2 to 4 minutes.
